APPARATUS FOR SUBSTITUTING GAS FOR ELECTRIC LIGHTS.

SPECIFICATION forming part of Letters Patent No. 274,181, dated March20, 1883.

Application filed August 21,1882. (No model.)

To all whom it may concern: as a cock revolved by a weight with one armBe it known that l, PATRICK B. DELANY, that is arrested by a projectionon the armaof the city and State of New York, have iuture-lever to holdthe cock in a closed posivented an Improvement in Automatic Appation. Asthe armature-lever flies back this 55 ratus for Substituting Gas forElectric Lights arm is released and the weight turns the cock, and theReverse, of which the following is a opens the same, and another arm isarrested specification. by the armature-lever and holds the cock open.
